Reef Fortress was the isolated stronghold of the Hapan Royal Family, on a small island in an ocean on the planet Hapes. In 23 ABY, Jedi trainees Tenel Ka, Lowbacca, Jacen Solo, and Jaina Solo stayed at the fortress. While they were there, Ambassador Yfra tried to kill them by sending their wavespeeder into a patch of dangerous carnivorous seaweed. After escaping from the seaweed, the young Jedi saved the Hapan matriarch, Ta'a Chume, from Bartokk assassins sent by the ambassador, thereby foiling Yfra's plot to overthrow the Hapan monarchy. Reef Fortress was also the location of an honor duel between Prince Isolder and Archon Beed Thane in 25 ABY. This duel decided the role of the Hapes Consortium in the war against the extra-galactic Yuuzhan Vong.
